Mostly in the mouth (mastication) and the stomach.
teeth
The tongue is involved in both mechanical and chemical digestion. It helps break down food into smaller pieces through chewing (mechanical digestion) and it also helps mix food with saliva, which contains enzymes that start breaking down carbohydrates (chemical digestion).
mechanical digestion is when you are breaking down food almost by hand. you're breaking it down manually. an example of mechanical digestion is chewing. it begins in your mouth and ends once you swallow.
No, digestive enzymes are not necessary for mechanical digestion. Mechanical digestion involves the physical breakdown of food into smaller pieces through actions like chewing and churning, while digestive enzymes are responsible for breaking down food chemically into nutrients that can be absorbed by the body during the process of chemical digestion.
Pepsin is an enzyme that plays a role in chemical digestion. It breaks down proteins into smaller peptides in the stomach.
what is responsible for chemical digestion in earthworms
welll it takes place in both mechanical and chemical
in the mouth when you chew
The mouth, by the teeth.
Mechanical digestion is mainly in the mouth.
The very minute food enters the mouth it goes through the digestion process. There are 2 digestive system function processes that take place in our body. These 2 processes are the mechanical digestion and the chemical digestion.
In the Mouth then the second is the Stomach
Mechanical digestion is a kind of digestion that takes place when food is chewed, mixed, or churned anywhere in your digestive track. two places it takes place are in the stomach and the mouth.
In the Mouth then the second is the Stomach
There is the small intestine, stomach, and the mouth, and that is all that i can think of. Hope this answer helps you people out there looking for three of the organs for mechanical digestion. But if not....... well that sucks for you.
Mechanical digestion, i.e. your body breaking up the food into smaller pieces, is largely meant to speed chemical digestion up. We know that the rate at which the chemical reaction takes place is dependent on four things: the physical state of the reactants involved in the reaction, the temperature at which the reaction takes place, the concentration of the reactants, and the presence of a catalyst. Each influences the rate of reaction in different ways. Mechanical digestion breaks the food into smaller pieces, i.e. changes the physical state. With the larger pieces broken into smaller ones, more surface area is exposed. With greater surface area exposure, chemical digestion can take place much more rapidly. However, if for some reason you could get just huge chunks of food down your throat without chewing it, your stomach still churns (mechanical digestion) and the contractions in your intestines also help to break up food. So technically yes, chemical digestion would take place, but at a much slower and inefficient manner.
In humans most mechanical digestion takes place in the mouth through chewing.
